LPE growth of GaAs by supercooling technique: Elimination of surface terraces

Abstract
The surface morphology of thin GaAs LPE layers grown on substrates misoriented from the (100) or (111) B plane is studied. The experiments demonstrate that surface terraces can be eliminated by using initially supercooled solutions. Very smooth surfaces are obtained for growth even on substrates miroriented 0–10° off the (100) plane.
